Description
An internal shutdown occurs after 100 ms.
This shutdown and the alarm signal can be reseted only by turning off and
restarting the supply voltage Upwr.
An internal shutdown occurs, when heat sink temperature reaches 95 ° C.
This shutdown and the alarm signal can be reseted only by turning off and
restarting the supply voltage Upwr.
Alarm signal, when the heat sink temperature reaches 80 ° C.
Alarm signal after 10 s overcurrent.
If the alarm signal is already active, the LED alarm lights off for 1 s and the
relay contact drops for 1 s, if a new alarm signal occurs.
- CAN Bus connection active,
- No internal shutdown active,
- Peak value of the excitation current < 75 A (15 minutes after response),
- Heat sink temperature < 75 ° C (15 minutes after response).
The alarm signal from the relay output or the LED display is identical.
An internal shutdown occurs, when the ICL was activated because of inrush
current above 250 A and the SW can not restart the unit.
This shutdown and the alarm signal can be reseted only by turning off and
restarting the supply voltage Upwr.
Description
LED lights up, when the power module is powered on and the DC-link
voltage is higher than 11 V DC.
LED lights up, when the excitation command is received from CAN Bus.
LED blinks, if there is no CAN Bus connection.
LED lights up, when the excitation current peak reaches 80 A.
LED keeps blinking for 15 minutes before it turns off, when the peak current
has dropped below 75 A.
LED lights up, when the heat sink temperature reaches 80 ° C.
LED keeps blinking for 15 minutes before it turns off, when the temperature
has dropped below 75 ° C.
